SPECIFICATION forming part of Letters Patent No. 440,770, dated November 18, 1890.

Application tiled June 2l, 1890. Serial No. 356,310. (No model.)

To @ZZ whom t may concern:

Be it known that I, OSCAR Louis GiLBERT, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented an additional improvement over my former invention in Car- Couplings, (embodied in application Serial No. 343,808, tiled March 13, 1890,) ot' which the following is a specification.

The entire invention relates to improvements in coupling and uucoupling railroadcars; and the objects ot' my improvements are to accomplish the coupling and uncoupling of cars by means of a swing-pin, its axle, and attachments, together with a link-lifter. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which-- Figure 1 is a front view of the entire mechanism; Fig. 2, a top View inside the drawhead on section M, Fig. l, showing the coupling pin and link as Well as the swing-bar in position for lifting the link. Fig. 3 is a side view of the mechanism inside the draw-head on section N, Fig. 2, showing the link when placed in position by means ot the swing-bar for coupling another car with draw-head of different height. Fig. 4 is afront view of the cross-piece on axle C, with a hook on each end and chain and weight attached in the center.

Similar letters refer to similar parts throughout the several views.

Letters A A A refer to the draw-heads.

Letters B B show the link when coupled.

Letters C C C illustrate the axle, which is run through the upper part of the draw-head.

LettersD D D show the coupling-pin, which is connected With the axle C inside the drawhead.

' LetterE refers to space provided for the link and pin.

Letters F F F represent the sWing-bar,which runs through the draw-head projecting from same on one side and being bent for a handle.

Letters G G G represent a piece of iron,the form of which is illustrated in the drawings. This is attached to the swing-bar F and rests in a recess in the bottom of the draw-head. The swing-bar being turned, this attachment will lift the link.

Letters H H show the cross-piece fastened to the end of axle C outside the draw-head. In the center of this cross-piece is attached a chain with weight. To each end of the cross-piece is a hook marked I.

Letters I I I illustrate the hooks on each end of the cross-piece I-I. These hooks serve the purpose of coupling and uncoupling when the chain with weight attached is placed there by rotation of the coupling-pin D.

Letters K K refer to the chain fastened to the center ofthe cross-piece l-I.

Letters L L show the weight attached to chain K.

Letter O represents an opening on top of the draw-head for the purpose of putting the pin through.

Having previously made application for Letters Patent for the combination of the coupling-pin ou an axle, link, and cross-piece with attachment-s, I do not now claim the entire combination herein speciiied; but

W'hat I do claim as my invent-ion, and desire to secure by Letters Patent, is-

The combination of the draw-head, coustructed as shown, with the axle provided with the swing coupling-pin, and having at one end the cross-piece II, provided with the chain and weight and the two hooks, and with the swing-bar F, bearing the link-lifter, all substantially as described. e
